The Brazil nut tree is one of the Amazon's longest living trees, of an age 1,000 years. Its flowers depend on bees for pollination. Once pollinated, a coconut-sized seed containing some tiny 20 seeds, develops for over 15 months before falling to the forest floor. They are found exclusively in Amazon forests since harvesting is exhausting, even for the strong. Apart from bees and the Brazil nut harvesters, the life of many other plants and animals is intertwined with this tree. The empty seeds fill with rainwater and provide breeding grounds for flies, frogs, all of which depend on these small ponds on the forest floor.. The major threat to the trees is forest clearing. Sustainable harvesting of Brazil nuts is therefore vital way to provide protection of forests and saving the Amazon.

1136. We can clearly understand from the passage that the Brazil nut

(a) has been harvested throughout South American countries as it is
beneficial for their economy

(b) is only found in Amazon forests because harvesting it requires
demanding work

(c) is the only food bees show interest in

(d) is the fruit of the longest living tree in Amazon region

1137. We can infer from the passage that when considered ecologically

(a) seeds of the Brazil nut spread through many countries of the world
through pollination

(b) the empty seeds provide breeding grounds for all the animals in the
Amazon

(c) bees depend mainly on the flowers of Brazil nut trees to survive

(d) the Brazil nut is important not only for some animals but also the
Amazon's survival

1138. It is clearly pointed out in the passage that

(a) since the Brazil nut tree only grows in the Amazon, it is the main
attraction of this region

(b) the process of pollination can be disturbed by the interference of bees

(c) the reason why the Brazil nut is important for some animals is that its
seeds serve like water ponds for them

(d) it is necessary to restrict the growth of the Brazil nut to save the
Amazon
